Schematic representation of the geometry in real and Fourier space. (a) A plane wave illuminates the sample. It is placed in vacuum and confined to the scattering volume illustrated by the green box. The signal at the detector plane is the superposition of the primary wave with wavevector [{\bf k}_{0}] and the scattered wave with wavevector [{\bf k}_{1}]. (b) The diffraction space is the reciprocal space of scattering vectors [{\bf q} = {\bf k}_{1}-{\bf k}_{0}] and contains the Fourier transform of the scattering potential [\varphi({\bf x})].
